Due to an error I've removed some active session db and dbxml from a living MapGuide server (2.5.2). Mapguide then aborted logging

15d375d0-7c65-11e3-8000-5254006ae79a_en_MTI3LjAuMC4x0AFC0AFB0AFA.db: unable to flush: No such file or directory
15d375d0-7c65-11e3-8000-5254006ae79a_en_MTI3LjAuMC4x0AFC0AFB0AFA.dbxml: unable to flush: No such file or directory
mgserver: DbEnvironment.cpp:239: virtual MgDbEnvironment::~MgDbEnvironment(): Assertion `false' failed.
./ line 8: 24225 Aborted                ./mgserver run

The relevant code in 2.5 branch is

229	MgDbEnvironment::~MgDbEnvironment()
230	{
231	    if (m_opened)
232	    {
233	        try
234	        {
235	            m_dbEnv.close(0);
236	        }
237	        catch (...)
238	        {
239	            assert(false);
240	        }
241	    }
242	}

While the problem is an error on my side, I would suggest to make MapGuide more robust, logging the error and continuing instead of asserting and aborting.

Aren't asserts noops in non-debug builds?

I'm observing this with aggressive zooming in/out and selection. Will do some more testing without the assert()
